<p>I just added a new UI test and didn't want to build a full rustc so I did <code>./x.py --stage 0 test src/test/ui</code>. but that builds LLVM so it takes forever (way longer than rustc -- and with LLVM being updated so often these days... I digress). Is it expected that this will build LLVM? it should use the stage 0 (bootstrap) compiler, I thought?</p>

<p>If it did, you would see tons of test failures for everything that's changed since beta?</p>

<p>So that seems like not what you want.</p>

<p>hm, fair. I thought I could avoid building a compiler but you are right, that makes no sense.</p>

<p>there were some cool plans at the all-hands to make it use pre-built toolchains :D</p>

<p>Yeah, I need to get around to it. It's one of those things that I really want to do but can never find the energy to</p>

<p><span class="user-mention" data-user-id="120791">@RalfJ</span> switching to system's LLVM was one of the best decisions to speed up my compiler workflow, see <a href="https://github.com/rust-lang/rustc-guide/pull/422/files" target="_blank" title="https://github.com/rust-lang/rustc-guide/pull/422/files">https://github.com/rust-lang/rustc-guide/pull/422/files</a></p>
